More info on HTEI came out yesterday. Turns out the company has been aggressively buying back its own shares (check out the news for the stock on Yahoo if it doesn't show up on Fool news for the stock here).

Reason this is important is twofold:

First, the press release noted that the company is now prohibited from buying more stock until earnings are released. It does not take much to figure that buying will resume after earnings...the low volume today shows as much...

Next, Laloggia notes that the three best signs of an impending takeover are 1. Beneficial ownership by an outsider that is buying the stock, 2. Insider buying and 3. Company buying back its own shares.
